Hereinafter in the claims where I have used the term or phrase mechanism for operating said devicesin due order. the same is to be understood as meaning any appro-' priate or-suitable mechanism which may be used for communicating to the several operative devices the movements necessary to enable such devices to perform their described functions, and such words are not to have the effect to in any way limit the scope of the claims to the particular mechanism for operating the several working devices which I have for convenience herein shown and described. t

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is a side elevation of a machine embodying my invention. Fig. 2 is a plan view; Fig. 3, a rear side elevation; Figs. 4 and 5, end views;.Fig. 6, an enlarged vertical sectional view on line 6 6 of Fig. 2. Fig. 7 is a vertical longitudinal section showing the punch for cutting the stars or spur-wheels. Fig. 8 is an enlarged detail view of the yielding guide forming a portion of the star-feed device, and showing, also, the pin or device for extracting the star from the star-feed slide in case the pivot-wire should not be inserted through the star. Fig; 9 is a detailed verti cal sectional view showing the device for feed ing the star-strip. Fig. 10 is a View of the star or spur wheel fencing as made by the machine, the same being full size; and Figs. 11, 1 2, 13, 14, 15, and 16 are detailed views illustrating the various steps or operations of the machine. in applying the star and pivot to the fence-wire. Fig. 17 is a detail plan view of the guide or slideway in which the horn D reciprocates, and shows, also, the spring-clamps d d, which guide and hold the spur-wheel while the pivot-wire is being inserted; and Fig. 18 is a detail plan view of the pivot-Wirefeed rolls.

In said drawings, A represents the frame of the machine; a a, the two fence-wires, which are fed parallel to each other through the machine; a, the pivot-wire; a, the star strip or band of sheet metal from which the stars are punched; a, the star punched from said strip; a, the pivot as severed from the pivot-wire, and a the hole in the star or spur wheel through which the pivot is inserted.

Bis the main driving-shaft of the machine, suitably journaled on the frame, having flywheel Band fast and loose pulleys B B. This main shaft is furnished with a series of cams by which the various operative parts or devices of the machine are actuated. The fence-wires are intermitting'ly fed through the machine by tached to the frame at c and having a spring, and threaded nut c", furnished with a handle, a, for turning the same, whereby the upper feed-roll, which is mounted on the piv oted arm a, maybe pressed against the lower feed-roll, which is j ournaled in the stationary frame.

D is a horizontal reciprocating horn or nose, over or around which the pivot-wire is bent, having holes cl d, through which the two fence wires (1 a pass, and provided with a central vertical slot, (2, to receive the spur-wheel or star at when it is fed forward into position between the fence-wires and in front ofthe pivot wire.

E is a vertical guide through which the starstrip a is fed.

F is a horizontallyreciprocating punch, and F the corresponding female die for punching the pivot-holes in thestar-strip. The female die F is secured in a suitable bed-block or frame-piece, F by a set-screw,f.

G is the punch, and -G the corresponding femaledie for punching out the stars orspurwheels from the starstri p.

H is a pusher or rod reciprocating through the hollow punch for pushing the stars through the female die Ginto the pocket k of the reciprocating star-feed slide K. The holepunch F, as well as the star-punch G, reciprocates back and forth in suitable guides, G". on the frame of the machine, and the punch F is secured to and operated by the same lever, G which operates the punch G. The lever G is pivoted to the frame at g, and is operated by a cam, G, on the main shaft B. The pusherrod H is operated by a lever, H, from the cam H on themain shaft B. The starstrip isfed down at intervals by a lever, E, pivoted to the .frame at FF, having a pawl, e, which engages the hole previously punched in the star-strip by the punch F, the punch F being withdrawn at the time the strip feed takes place- The lever E is operated 'from a cam, E on the main shaft through a lever, E, pivoted at E to the frame, and a connecting-link, E pivoted to said'levers E E. A spring, E, serves to 'move said lever E one way. The star-feed slide K has beveled edges is, and reciprocates between or upon friction guiderollers k having peripheral grooves lcitherein, which rollers arejournaled upon the frame A or an inclined projecting bar, A, secured rigidly thereto.

The slide K is operated by a lever, K,'pi voted at K to the frame of the machine, carry ing a friction-roller, K on its short arn1,which is operated by a cam, K, on the cam-shaft B. This lever is connected to the slide K by a pivotal link, K, which passes through a hole ICC Ils

The shaft L of one of these wheels is intermittingly revolved to feed the pivot-wire forward the requisite length for a pivot at intervals by the pin-wheel L on the end of said shaft, the pins of which engage the spiral cam L on the main shaft. The shaft of the other feed-wheel, the Iefthand one, as seen in Fig. 5, is journaledinan eccentric bearing in the usual manner. This eccentric bearing has an arm, 1, to which a spring, Z, is attached to press the feed-wheels together and keep the requisite tension upon the wire. Pivoted to this arm Z is a lever, Z1, connected by a pivoted link, Z, to the frame,whereby the rolls may be relieved from the tension of the spring when it is desired to stop the feed of the pivot-wire. The link is slightly curved, as shown in Fig. 2, so that the lever Z may be carried past its center, as shown in the dotted lines, and thus be selflocking.

M is a yielding guide bar or plate secured to a horizontal sliding pin, m, mounted in the socket m, secured to the frame of the machine and having a spiral spring, m which presses said guide-bar M against the star-feed slide K, and thus serves to keep the star in placein the pocket of said slide. The guidebar M is made yielding to accomodate spurs of different thicknesses, as the sheetmetal strips from whlch they are out are not always of a uniform thickness throughout. The guide-bar M is also furnished with a yielding pin or pawl, m secured to the plate m", which surrounds the sliding pin m, for the purpose of extracting the star from the feed'slide K when said feed-slide is withdrawn in case a star should fail to be caught by the pivot-wire or for any reason be retained in the feed-slide as it recedes.

N is the stationary knife, having a hole or opening, 12, through which the pivot -wire passes, and N the vertically reciprocating knife by which the pivot is severed from the wire. The upper flat end of the knife N serves as one of the verticallyntoving pivotbenders, and N is the other corresponding bender-slide.

N is the bottom clincher,which serves to sup port the pivot wire below and also to form the final bend, a", in the middle of the pivot. This clincher-bar is furnished with a vertical slot, n, for the star or spur wheel. The knife and bender-bars N N and clincher-bar N are all secured rigidly to a reciprocating or oscillating head, N, and are operated simultaneously. These several tools might all be formed in one piece; but it is preferable to make them separate for purposes of independent adjustment, ease of manufacture, and convenience of re placement when worn or broken. The benders N N have slight grooves or notches n for the ends of the pivot-wire. The reciprocating head N is operated by a can], N, on the driving-shaft B through a lever, N, pivot N, connecting-link N, and swinging arm N piv oted at N to the frame, to the head or face of which arm N the head N is securely bolted. The cam is of such form as to give the knife, benders, and clincher the required movements, as before described.

P P are the horizontally or inwardly moving benders, which reciprocate in suitable guides, P, over the ends of the benders N N These benders are simultaneously operated from the cam P on the driving-shaft B through a lever, P pivotal link P, and rocking catnhead P having inclined cams or groovespp in its peripheral face, in which eamsp p fitstuds p p, secured to the sliding benders P P. The reciprocating nose or horn D is moved in and out, as required, in its guide or slide way D by means of a cam, D on the main shaft, which acts against an arm, 1), on the vertical rock-shaft D, said rock-shaft having an upper arm, D, the outer end of which engages a notch, d in the sliding horn D.

The fence-wire-feed wheels G O are intermittingly rotated to feed the fence-wires forward, as required, by a cam, O, on the main shaft, which operates to vibrate a lever, 0 pivoted at O to the frame, and which is furnished at its upper end with a segment-gear, c, that meshes with a gear, 0, journaled loosely on the shaft 0 of one of the feed-wheels. To the inner face of this loose gear 0 is pivoted a pawl, 0 that engages the teeth of a ratchet, e, se cured to the shaft 0 of the feed-wheel O. The upper feed-wheel O, or its shaft, is geared to the shaft of the lower feed-wheel by the spurgears c c.

Q is an upper guide and tension-clamp for the star-strip.

R R are straighteningrollers for the pivotwire.

Just below the slotted horn or nose D, I secure a pair of springs or clamps, d" d, to the frame ofthemachine, havingoutwardly-curved ends to guide the spur or star to place as it is fed or moved into position by the star-feed slide K. These spring-clamps serve, also, to clamp and hold the spur-wheel while thepivot is being inserted through its hole and bent around the fencewires.

I hereby disclaim as not of my invention the machine shown and described in Patent No. 313,090.
